Testimonials

“ProtoCAM's turnaround times are exceptional, and their prices compared to others are always better. There's a lot more value added in working with ProtoCAM.” — Matthew Bellenoit, B. Braun Medical

“ProtoCAM's best attribute is their attention to detail and customer service. Their willigness and desire to keep in touch with me is impressive, and physical walkthroughs ensure me quality standards are being met.” — Todd Frick, Clair Brothers Audio Systems

“When we need to make a change, ProtoCAM always accomplishes it accurately. We see the results we planned on consistently. They do a very good job providing quality products.” — Rory Kiphart, Biomet

“I’ve worked with a lot of different rapid prototype houses and I've consistently ended up back at ProtoCAM. Quality is key and they deliver consistently. They’ve given us a significant advantage over our competitors.” — Dan Dunham, XOS

“There are many companies in the rapid prototyping business that are automated and there’s no personal interface. That's the big difference between ProtoCAM and other companies.” — Jim Eldon, Design Associates

In selective laser sintering (commonly known as “SLS” or “LS”), 3D parts are created by fusing (“sintering”) powdered materials with an infrared laser beam. The result is strong, durable and machinable parts with thermoplastic material properties similar to those of injection molded prototypes.

About SLS

The use of selective laser sintering prototyping (commonly called SLS prototyping or 3D SLS prototyping) is ideal for product prototypes that require exceptional strength or must closely approximate the properties of thermoplastics.

In selective laser sintering (SLS), three-dimensional parts are created by fusing (“sintering”) powdered thermoplastic materials such as nylon and elastomers with the heat from an infrared laser beam. Thin powder layers are repeatedly laser sintered, creating the desired 3D piece based on a 3D CAD model.

There are several key differences between prototypes created using selective laser sintering (SLS) and prototypes created with stereolithography (SLA). These include:

Prototype strength: SLS prototypes are generally stronger and more durable than SLA prototypes.

Material properties: SLS allows product prototypes to be created with material properties similar to those of injection molded prototypes.
